Abstract: 263,334. Timmins, E. Feb. 11, 1926. Trouser presses and stretchers. - In a combined press and stretcher the trousers are placed between a board a and a bow-shaped spring h which latter is shown in the drawing in its depressed or operative position. A lever arm c<2> which is wedge-shaped swings in bearings b and is pressed against the plate spring by an adjustable spiral spring e. The spring h is narrower than the board a and these elements may be mounted in pairs, as shown in Fig. 2, spaced apart by strips l, and each engaging its corresponding edge of the trousers. By means of a cord or chain m, a coat may be hung up in addition to the trousers. In a modification, resilient pressure against the plate spring h may be obtained by a single bow-shaped spring of opposite contour to the spring h and engaged by levers as before but without a spiral spring mounting. In a second modification, a pair of bow-shaped springs are employed to act on the spring h.

Patent GB-470187-A (GB)
Title: Improvements relating to the preparation of oxygen-containing compounds of cerium
IPC: C01F17/235
Filed: 1936-02-10
Abstract: In a process for recovering cerium and other rare earth metal compounds from a mixture of their sulphates, the latter are reacted, in the presence of an aqueous solvent, with the nitrate of a metal, such as calcium or barium, giving a sparingly soluble sulphate, the resulting solution of rare earth metal nitrates is treated, as by electrolytic oxidation, to convert the cerium to the tetravalent form, the cerium then separated, as by hydrolysis, and the remaining rare earths precipitated, as by an alkaline earth metal compound, with recovery of nitric acid for instance as a nitrate which may be re-introduced into the process, if desired. Hydrolysis of the ceric nitrate may be effected by adding the nitrate solution to a boiling solution of dilute sulphuric acid and boiling the mixture for some time.  The mother liquor from the hydrolysis may be neutralized with calcium carbonate to separate residual cerium, and then be heated with addition of lime to separate the other rare earths, and recover calcium nitrate.  Or, when barium nitrate is used, the mother liquor may be boiled with barium carbonate to precipitate the rare earths and recover barium nitrate.  In a modification, nitrates of the other rare earths may be crystallized from the mother liquor, and the free nitric acid remaining in solution be re-introduced into the process, for instance, to the step of oxidizing the cerium nitrate.

Title: Improvements in or relating to the production of odourless solvents
IPC: C10L1/183
Filed: 1962-02-02
Abstract: A heavy alkylate (being that material boiling in the range 180-310 DEG  C. which is produced when a feedstock containing a major proportion of isobutane is reacted with a feedstock containing a major proportion of normal C3-C5 olefinic hydrocarbons, in the presence of an alkylation catalyst) is fractionated to obtain a cut boiling in the A.S.T.M. distillation range 180-210 DEG  C., and subsequently treating this cut with activated bauxite, preferably at ambient temperature and atmospheric pressure, for example, by percolation downwards through a stationary bed.  The product is an odourless solvent, which may be used for paints, lacquers and resins. The bauxite is preferably of particle size - 16 + 100 mesh B.S.S., and is preferably activated by roasting.  The fractionation may be effected either by normal or by steam distillation, in which latter case the cut may be passed through a salt filter to remove water prior to being passed over the activated bauxite.  The thus treated material may be stabilized and prevented from forming odours by the addition of a minor proportion of an alkyl substituted phenol of general formula <FORM:0967830/C4-C5/1> where R1, R2, R3 are alkyl groups, at least R1 or R2 being tertiary butyl.  Preferably R3 is methyl.  Preferably the stabilizer is present in amount 0.005 to 0.015% by weight.  The preferred stabilizer is 2,6-di-tertiary-butyl-4-methyl phenol.

Patent GB-366728-A (GB)
Title: Improvements relating to electrical communication systems
IPC: H04B1/50
Filed: 1931-02-10
Abstract: 366,728. Wireless and wired wireless signalling. KOLSTER-BRANDES, Ltd., Cray Works, Sidcup, Kent.-(Wired Radio, Inc. ; 60, Broadway, New York, U.S.A.) Feb. 10, 1931, No. 4158. [Class 40 (v).] A two-way carrier-wave signalling system employs a valve circuit at each station, and each valve is brought to oscillation by reaction from the valve at the other station. Fig. 2 shows a line system, in which the valve 3 at station 1 has its grid circuit connected across the line at the mid-points of the hybrid coil 22, whilst its plate circuit is coupled inductively to the line coils. The valve 31 at the other station 2 has its circuits connected in identical manner. Owing to the networks BN balancing the line impedance, there is no local backcoupling at either station ; but the plate circuit of valve 3 is coupled to the grid circuit of valve 31 and vice versa and each valve is thus kept in oscillation. Residual local reaction may be neutralized by balancing condensers. A microphone 24 coupled to a modulating- valve 27, and a telephone 29, are provided at each station. In a modification, Fig. 3 (not shown). for radio transmission, the line is replaced by two pairs of loop aerials forming tuned grid and tuned plate circuits of each valve. Local back-coupling between the transmitting and receiving aerials is neutralized by a reversed back-coupling between plate and grid circuits ; but each plate circuit is coupled to the grid circuit at the distant station through a radiation link. In a further modification shown in Fig. 4, each station has a single aerial which serves both for transmission and reception at different frequencies. The aerial 51 at station 1 receives oscillations from the remote station and combines them in a detector 55 with oscillations generated locally by the valve 56. One of the combination frequencies, say the difference frequency, is selected and amplified by a valve 57 and passes to the detector 58 and telephones 59. The difference frequency is also fed through an amplifier 63 to a valve 60 where it is modulated by a microphone 24 and modulator valve 27. The modulated output is fed to the aerial and is radiated at a frequency less than the incoming frequency. The aerial 51 has two resonant frequencies, and the transmitting frequency is blocked from the receiving circuits by a rejector circuit 54. At the other station, the circuits are identical, except that the sum frequency instead of the difference is selected for feeding back to the aerial for transmission.

Title: Improvements in or relating to clutch devices for the driving mechanism of machines
IPC: F16D67/02
Filed: 1949-02-18
Abstract: 669,566. Clutches. JACKSON, N. V., and MOLINS MACHINE CO., Ltd. Feb. 14, 1950 [Feb. 18, 1949], No. 4498/49. Class 80 (ii). [Also in Group VI] A clutch device, particularly applicable to a cigarette making machine, comprises a driving member 44 with a single ratchet toothed member 99 on a sleeve 91 thereof and a driven member 97 on a shaft 45 carrying a ratchet pawl 98 adapted to engage with the ratchet tooth 100 of member 99 to effect a driving connection between members 44 and 97. Disengagement of the drive is effected by raising a lever 107 with an abutment 106 into the path of the tail 105 of pawl 98 which at the same time releases a spring-loaded lever 108 to apply a brake shoe 197 to a friction groove in the driven member 97 to bring it to rest instantaneously. The lever 107 can then be released but re-engagement of the pawl 98 is prevented by a baulking member 92 on the sleeve 91 having a slot 96 therein which is moved out of alignment with the ratchet tooth 100 by a spring 104. When the drive is to be re-engaged however the lever 108 is moved against its spring 109 to release the brake shoe 197 and apply another shoe 94 to a friction groove in the baulking member 92. This re-aligns the slot 96 with the ratchet tooth 100 and allows the pawl 98 to be moved by its loading spring to engage the tooth 100 to effect the drive. The lever 107 then drops into the position shown to hold the lever 108 against return movement by its spring when released. Specifications 664,690 and 669,557, [both in Group VI], are referred to.

Abstract: 929,461. Timed control of electric circuits. CHAMBERLAIN & HOOKHAM Ltd. Jan. 24, 1962 [Feb. 7, 1961], No. 4498/61. Class 139. [Also in Group XXIV] In a process timer of the kind wherein cams 11 fast with a shaft 12 cyclically operate a series of switches or valves, the shaft 12 is driven from a reversible electric motor 16 through a gear 17 and cam 15 which oscillates a pawl of a pawl-and-ratchet mechanism 14, the ratchet wheel of which is fast with the shaft 12. The gear 17 which drives the cam 15 at different speeds in the same direction by reversing the direction of the motor 16 comprises a pinion 22 driven from the motor 16 through gears 27, 26, 25, 23 and carried by an arm 35 which for one direction of rotation of the motor 16 swings to mesh pinion 22 with one pinion 29 of stepped idler pinions 28, 29, the other 28 of which meshes a pinion 31 fast with a pinion 19 which drives the cam 15 at one output speed, whilst the reverse rotation of the motor 16, the motor 35 swings to mesh pinion 22 directly with the pinion 31 for the other output speed. Manually controlled one-way detents 37, 38 prevent rotation of the gear 26 and thus drive at the wrong output speed if the motor is accidentally started in the wrong direction.

Title: Improvements in or relating ot engine cooling and passenger compartment heating apparatus for motor vehicles
Inventor: PLACKETT ANTHONY GEOFFREY
IPC: B60H1/00
Filed: 1967-01-30
Abstract: 1,205,941. Heating and cooling vehicles; cooling vehicle engines. SMITHS INDUSTRIES Ltd. 18 Jan., 1968 [30 Jan., 1967], No. 4501/67. Headings F4H, F4U and F4V. In a vehicle air-conditioning system in which the air is heated or cooled and also filtered the temperature of air entering the passenger compartment is sensed and control means responsive to a change in temperature actuates valves to maintain the original air temperature. Air from outside the vehicle enters via an intake 10 and flaps 8 where fans 11 force the air through the vehicle radiator 4 and out through flaps 14. If a flap 20 is open and a flap 16 is shut a mixing compartment 17 receives heated air. If both flaps 16 and 20 are partly open (Fig. 3) some hot and some cool air can be delivered to compartment 17. Alternatively, only cool air may be delivered via flap 16 to compartment 17. Some recirculated air from the passenger compartment can be added to the air in compartment 17 and passed along a duct 18 to the various seat positions. Air is exhausted from the passenger compartment via louvers 29. The flaps 8, 14 open and close in response to the temperature of the coolant in radiator 4, which may comprise several units connected in parallel. A thermostat 53 in the engine cooling system (Fig. 7) has a member 54 that projects to engage an arm 50 on a linkage controlling the movement of the flaps 8, 14, the amount by which the member 54 projects is dependent upon the coolant temperature. Movement of the linkage also actuates micro-switches 62 controlling the energizations of solenoids 63 in a control circuit for fan motors 12 so that as the coolant temperature rises the fans speed up and vice versa. The refrigerating system comprises a condenser (32, Fig. 1, not shown) placed adjacent and parallel to the radiators 4 and an evaporator 33 in the air mixing compartment 17. The compressor is driven via a clutch from the vehicle engine. In hot weather a flap which normally permits some recirculated air to enter the passenger compartment is closed and the closing of this flap also operates a switch to bring the refrigeration unit under the control of a thermostat. The control system includes three thermistors which sense the outside temperature, the passenger compartment temperature, and the temperature of air entering the passenger compartment from the duct 18. The desired temperature can be manually pre-set. The control system also includes a bridge network, amplifiers and a reversing electric motor controlling the flaps 16, 20. If for example a change occurs in the temperature in duct 18 a signal is applied to one of the amplifiers and the motor is energized to adjust the flaps 16, 20, simultaneously, the bridge network is rebalanced.
